SAFE OR VAULT.

Specification of Letters Patent.

Patented Oct. 9, 1906.

Application filed September 11, 1903. Serial No. 172,712-

To all whom it may concern:

Be it known that we, WALTER BRINToN, residing at High Bridge, in the county of Hunterdon, and WALTER GASTON, residing at Plainfield, in the county of Union, State of New Jersey, citizens of the United States, have invented certain new and useful Im provements in Safes or Vaults, of which the following is a specification.

This invention relates to burglar-proof safes or vaults, the object of the invention being to provide an improved safe or vault comprising a body and a door formed each as an integral member or structure, the body being so made up that when formed of un machineable metal having therein a predetermined quantity of manganese it will present greater resistance to burglarious or mob attacks than when constructed as heretofore.

In the drawings accompanying and forming a part of this specification, Figure 1 is a front elevation of this improved safe or vault. Fig. 2 is a perspective view thereof. Fig. 3 is a rear view, and Fig.4 is a vertical sectional view thereof.

Similar characters of reference indicate corresponding parts throughout the several figures.

This improved safe or vault is made up of two integral castings, one comprising a body 3, having a circular, preferably cone-shaped, doorway 4, and the other a circular door 2, conforming to the shape of the doorway. The body is provided around its doorway with an inwardly-projecting ring projection, or flange 6, which not only provides a means of elongating the jamb, in which is formed a step or offset 7, but also constitutes a means of reinforcing the safe-body. This cast integral body 3 is of peculiar formationthat is to say, it partially resembles a cylinder and partially resembles an oblate spheroidand comprises a substantially plane or flat rear wall 13 and an annular portion made up of a cylindrical part 20 and a pair of parts 21 and 22, curved transversely to such cylindrical part, each having substantially a quadrant curvature, that, as 21, at the forward end of the cylindrical portion terminating in the doorway and that, as 22, "at the rear of such cylindrical portion merging into the rear wall 13 of the body. This organization thus provides a structure which is of arched formation and without angles at any point and a safe-body entirely different in shape from a spherical or a rectangular body.

The integral cast door 2, which is supported exteriorly of the safe-body by suitable lugs 9 and a hinge 10, such as a crane-hinge, fits tightly within the doorway and is made up of a relatively planeor flat portion or portions 12, which do not appreciably project beyond the front quadrant surface 21 of the body, and the rear wall 13 of the body and the front portion or portions 12 of the door are in substantially parallel planes. This door fits into the doorway or jamb in such manner that it is at its outer edge protected by a projection or enlargement integral with the body and forming a part of and merging into the forward quadrant curved part and which, while it may be of various formations, is shown as a bead or swell 5. To support the body, a suitable base 15 is provided, having a seat portion 16 for the reception of a similarly-shaped portion 17.

By forming the casting of unmachineable metalsuch, for instance, as manganese steel or steel having therein a predetermined quantity of manganese (by which we mean that steel disclosed in the several patents of Hadfield and which has in it a certain percentage of manganese, the predetermined quan tity of which usually varies from about five or seven per cent.- to about twenty or thirty per cent. the preferable predetermined quantity of manganese varying from about eleven or twelve per cent. to about sixteen or seventeen per cent.)in the manner set forth, and

especially when such casting is subjected to heat treatmentthat is, after being cast is heated up to a predetermined temperature and then cooled by suddenly immersing it in watera structure is obtained which not only affords superior resistance to attacks, but it can be more readily cast and treated, since it has been found that steel having a predetermined quantity of manganese therein can be cast with greater facility and with higher re sisting qualities when the casting is made in the manner set forth than otherwise, as there is less liability of internal strains setting up within the mass, and the casting can be made more uniform, which is a great advantage in a burglar-proof safe made of this steel, since the structure can then be uniformly heated,

thus avoiding internal strains in the metal, all of which are important in a burglar or mob proof safe or vault.

For securing the door in its jamb or seat' some suitable means may be provided, shown herein as bolting mechanism, comprising bolts passing through openings in a flange of the door and into openings or an annular recess in the door-jamb. These bolts may be shifted by any suitable means adapted for the purpose.

We are aware that spherical and cylindrical safe-bodies have been heretofore provided; but so far as we are aware we are the first to provide a cast safe or vault body of unmachineable metal having therein a predetermined quantity of manganese and having the organization described. and the peculiar characteristics set forth.

By the provision of'a safe or vault having the peculiar formation described and made of two integral castings of steel of the character described, a body and a door, the former so formed that the door edge is protected by a projection or enlargement around the same, we believe that a superior structure for resisting attacks is not only obtained, but one which, as hereinbefore stated, can be cast and treated. with better results than other forms of such structures.

We claim as our invention 1. A safe or vault comprising an integral body and a circular integral door, each cast of-unmachineable metal having a predeterminedquantity of manganese therein, said body being of such formation that a more perfect equalization of the strains resulting from heat and shrinkage is obtained, and comprising a substantially flat rear wall and an annular portion made up of a cylindrical part and a pair of parts curved transversely to such cylindrical part, that at the forward end of the cylindrical part terminating in the doorway and that at the rear of the cylindrical part merging into the rear wall of the body, and said door having a relatively plane or flat outer surface or surfaces which do not appreciably project beyond the front curved surface of the body.

2. A safe or vault comprising an integral substantially uniform body and a circular integral door, each cast of unmachineable metal having a predetermined quantity of manganese therein, said body being of such formation that a more perfect equalization of the strains resulting from heat and shrinkage is that at the rear of the cylindrical part merging into the rear wall of the body, and said door having a relatively plane or flat outer surface or surfaces which do not appreciably project beyond the front curved surface of the body, the rear wall of the body and the front wall of the door being located in sub stantially parallel planes.

A safe or vault comprising an integral body and a circular integral door, each cast of umnachineable metal having a predetermined quantity of manganese therein, said body being of such formation that a more perfect equalization of the strains resulting from heat and shrinkage is obtained, and comprising a substantially flat rear wall and an annular portion made up of a cylindrical part and a pair of arts curved transversely to such cylindrica part, and each having substantially a quadrant curvature, that at the forward end of the cylindrical part terminating in the doorway and that at the rear of the cylindrical part merging into the rear wall of the body, and said door having a relatively plane or flat outer surface or surfaces which do not appreciably project beyond the front curved surface of the body, said body having around its doorway an integral projection or enlargement forming a part of and merging into such front quadrant curved art. p WALTER BRINTON.
